Hypertension: Hypertension is defined as blood pressure higher than 14090 mmHg. A diagnosis of hypertension may be made when one or both readings are…
Some degree-4 expressions hide squares after a small trick. The sum a^4 + a^2 b^2 + b^4 is not a perfect square as written, but adding and subtracting a^2 b^2…
Zeros give x-intercepts; denominator zeros mark exclusions and possible vertical asymptotes.
No concentrations, no how to grow resistant colonies, no how to share plasmids in a lab. Pesticides on insects can be the same selection story (named). No…
A Bar Magnet is a rectangular piece of magnetic material (such as iron, steel, or an alloy like Alnico) that produces a permanent magnetic field. The…
Repeated linear factors need every power; irreducible quadratics use a linear numerator.
Feature: Aerobic Respiration: Anaerobic Respiration; Oxygen requirement: Requires oxygen: Does not require oxygen
A locus is the set of all points that obey a rule. In plane geometry the usual Class 9 loci are: a circle (fixed distance from a point), a perpendicular…
1. Polishing – Waxes are effective in polishing. 2. Waterproofing – Waxes provide waterproofing. 3. Anti-fouling – Waxes prevent fouling…
Modular Design is the practice of dividing a system into separate, independent modules, where each module performs a specific task and can be developed,…
A closed pipe supports stationary waves with a displacement node at its closed end and an antinode at its open end. Its allowed wavelengths are λₙ=4L/(2n−1),…
Bronsted-Lowry Acid An acid is a proton (H⁺) donor. Simple explanation: A Bronsted-Lowry acid gives away a proton (H⁺). Bronsted-Lowry Base A…
Any integer over any non-zero integer is rational: 34, -52, 71. The word comes from ratio. If you can write the number as a fraction of integers with b !=…
Radio waves, microwaves and infrared are lower-frequency regions of the electromagnetic spectrum compared with visible, ultraviolet, X-rays and gamma rays.
Effects of increased connectivity on people refers to the positive and negative impacts that enhanced connectivity through computing technologies has on…
Everyday angles in this book use the sexagesimal English degrees system. One full turn is 360 deg. Each degree splits into 60 minutes, and each minute splits…
If magnitude grows without bound near x=a, x=a is a vertical asymptote; signs may differ by side.
sin(arcsin x)=x on [-1,1], but arcsin(sin x)=x only inside the principal interval.
Biology is the study of living organisms. It helps us explain how living things relate to one another and to their surroundings. The word "biology" comes from…
An aqueous solution is formed by dissolving a substance in water. Simple explanation: An aqueous solution is simply a solution where water is the…
The angle between a tangent and chord equals the angle in the alternate segment.
Limiting reactant. Ester eq: never all product unless you shift. Quote 2-3 s.f. as the paper. Low yield: side products, incomplete reaction, loss on transfer —…
